Gypsum is added to mushroom growing substrates providing calcium and sulfur.

 

Gypsum also helps spawn substrate break-up making it easier to mix when needed.

 

Use at a 2-5% ratio for best results. This usage rate is best measured off the dry-weight of the substrate. 

 

Can be beneficial for all mushroom kits and beds.

 

Gypsum is generally PH-7 meaning it is neutral and does not affect the substrate's PH much.

TESTIMONIALS

"Excellent service!

Sporeshift have consistently got the best service of any online provider I have used. From the time of order to delivery the communication is great. I frequently wonder why other businesses can't to it the way they do. Excellence in action. And no, I am not their mother ... just a satisfied customer and mushroom lover. :)"

"As a budding mycologist I just want to say how much I appreciate the investment in getting these new Species/ Phenos approved through MPI. I do hope you are aware that it opens the door for ALL of us here in NZ to learn about, grow and study an otherwise inaccessible taxonomical branch and that this kind of effort is extremely appreciated!"
